add custom field value directly from site WordPress

David Navarrete answers:

Hi is easy.. you have two kindes of custom fields, for post and for author.

you problem should be for author you need this function update_user_meta($user_id, 'name', 'value')

now for create a user i have this code.


http://pastebin.com/wFyCjG3r

you can call this code for jquery like this

$('a#save').click(function(){
datos = $('form[name=submit-user]').serialize();
$.ajax({
url : '/save-user/',
type : "GET",
data : datos,
sucess: function(msg){
alert('sucess');
}
});
return false;
})

if you need more help, tell me

pd: sorry for my bad english

Imo, custom fields is a bad idea for this.
You should use MySQL to archieve something like this.
When user signs up to an activity, it's username and activity ID is added to some new table.

It'll be easier to manipulate later, trust me.

If you use the Gravity Forms plugin which, in my opinion is the best way to create forms with WordPress, this is built into it.

You can do all of this and much more.

You'll notice that that isn't an affiliate link. I suggest it because I use it for all this type of thing.

Let me know if you need any further explanation.

Put this in your loop


<form action="" method="post">
<input type="text" name="Name" value="username1">
<input type="hidden" name="toPost" value="<?echo $post->ID; ?>">
<input type="submit" value="Submit" name="submit">
</form>


and this somewhere out of the loop:



<?php

if(isset($_POST['submit'])) //If submit is hit
{


$name = ','.mysql_real_escape_string($_POST['Name']); // fetch user input from the form. You could use user_id or username
$toPost = $_POST['toPost']; // our post_id to insert username


$result=mysql_query("UPDATE wp_postmeta SET meta_value=concat(meta_value, '$name') WHERE post_id=$toPost AND meta_key='Name'");
//SQL query: add to field "Name" new username

// uncomment for debug
//print mysql_affected_rows();
// print mysql_error();


if(!$result) die('Error: '.mysql_error());
else echo 'Inserted row with id='.mysql_insert_id();
}

?>



This will add the value of form to post you chose.
Finally you could insert user_id or his username and delete the textarea
